1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The infrapatellar fat pad (IFP), an adipose tissue located in the anterior knee joint, is hypothesized to absorb shocks and aid in joint lubrication. We investigated the consequences of IFP removal on joint friction and damping in an in vitro animal model. The hindlimbs of female New Zealand white rabbits were dissected to retain the knee ligaments, joint capsule, and patellar retinaculum. Knees were mounted in a pendulum with the knee joint serving as the fulcrum while keeping the quadriceps tendon unloaded to assess joint friction and damping in each knee for three conditions: Control, Sham, and no IFP (IFP-R). Friction and damping were assessed under a 15N tibio-femoral joint load (40 % of body weight) at three flexion angles (50°, 100°, and 130°), and gyroscopic data were recorded to obtain the time decay of amplitude. Two models, a linear friction and an exponential decay friction model, were fit to the amplitude decay over time. The linear model provided Stanton's joint boundary friction coefficient (μ
